AUDIX D4 Professional dynamic microphone for floor tom and bass drum

Hypercardioid Dynamic Drum and Instrument Microphone for Instruments Requiring Additional Bass Response

With a wide frequency response of 40 Hz - 18 kHz and the ability to handle SPLs in excess of 144 dB, the D4 is an  excellent choice for miking instruments requiring precise, low frequency reproduction such as large rack toms, floor toms, cajon, djembe, tympani, leslie bottom, bass flute, saxophone and baritone saxophone, trombone, acoustic bass, bass cabinets and small kick drums.

The D4 is lightweight, compact and easy to position.  Used for stage, studio and broadcast applications, the D4 is designed with a hypercardioid pickup pattern for isolation and feedback control.  The D4 is also equipped with a VLM™ diaphragm for natural accurate sound reproduction. 

Precise artistic work deserves precise artistic craftsmanship. A classic by now, the CMS Series CK 1 capsule from AKG was a best seller from the moment it was launched in 1969. Comprising a range of interchangeable capsules and preamps as well as then innovative, dedicated accessories, the CMS Series from AKG quickly became a legend. It was discontinued in 1993. Responding to growing demand from recording engineers, AKG decided to produce the C 451 B with identical acoustical behaviour of the popular original C 451 EB + CK 1 microphone again, with dramatically improved specifications and outstanding price/ performance. The capsule of the new version is fixed permanently to the preamp to eliminate the mechanical problems of the screw joint. Using an extremely light diaphragm, the new C 451 B is almost totally insensitive to handling noise. An all-metal body provides excellent protection from RF interference and the microphone is rugged enough to give excellent results even under very harsh conditions.

The C 451 B is an excellent tool for accurately capturing signals rich in transients such as drums, overhead miking, or other instruments with a percussive sound. The airy sound, high overload limit of the capsule and electronic circuitry, and improved engineering details of the C 451 B are a solid foundation for creating another legend.

The matched pairs consist of two microphones that are within 1 dB to each other in sensitivity and also within 1 dB to each other in the range of 200 Hz to 15,000 Hz of the individual frequency response when used in cardioid mode and are selected from a large quantity of individual microphones using the described criteria by using a proprietary computer program.

Using this matched pair for stereo recordings utilizing various techniques will provide for a good and stable balance without frequency-dependent shifting of the stereo panorama.

The kit includes all the standard accessories of the individual package along with a stereo bar and proof of performance charts in an attractive carrying case (Soundtool case, middle size).

Technical Data

NEW Wider mounting base capable of accommodating a larger range of microphone stands. Even works with the LP Claw.

Specifically engineered for drum and instrument applications, the Beta 56A's compact, pivoting design makes it the ideal choice for these applications.

Its extremely uniform supercardioid pickup pattern provides high gain before feedback and excellent rejection of unwanted noise. A built-in dynamic locking stand adapter with an integral XLR connector simplifies installation. The stand adapter keeps the microphone securely in place, even if it is struck by a drumstick. Typical Beta 56A applications include close miking of tom-toms and other percussion instruments, as well as guitar amplifiers, brass instruments, and woodwinds.

• Built-in stand adapter with dynamic locking system and XLR connector simplifies setup and provides greater flexibility
• Uniform supercardioid pattern for high gain-before-feedback and superior rejection of off-axis sound
• Compact design reduces stage clutters
• Hardened steel mesh grille resists wear and abuse
• Neodymium magnet for high signal-to-noise ratio output
• Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration
• Frequency response: 50 to 16,000 Hz

The supercardioid e 906 instrument microphone was especially designed for
guitar amplifiers, but it is also an excellent choice for percussion and brass
instruments.
